  <div>
   <div class="section">
    <h4 class="sectiontitle">Symptom</h4>
    <p>After the GraphBase service is installed on the MRS platform, metadata tables <strong>meta_graph</strong> and <strong>graphbaseORM_systemNotifications</strong> are created in the default namespace of the HBase application. If the GraphBase service is not installed in the target cluster, the restoration will fail.</p>
   </div>
   <div class="section">
    <h4 class="sectiontitle">Possible Cause</h4>
    <p>When restoring metadata tables <strong>meta_graph</strong> and <strong>graphbaseORM_systemNotifications</strong> of the GraphBase service, use the required GraphBase service to verify the table information. Because the GraphBase service is not installed in the target cluster to be restored, the table information fails to be verified and the restoration job fails.</p>
